tion with staples, so that it will be as on 
hinges. 
Now, with the other smooth board (c), 
Pig. 4, adjust a similar piece of wood as 
an A, but wider in the middle, about II in. 
Make two pieces 142 long, I thick, and Ik 
at widest part, Eig. 4. They are screwed

one on each side of the board, i in. from 
edge, the top even with top of board. 
Through the middle piece of board (c) 
a handle is adjusted. It is 164 long, i 
»thick, 14 wide. It fits the middle piece, 
and is held there by another steel pin 
running through handle and board. 
The end of handle is held up by two 
pieces about 44 long, f thick, 1 wide, one 
on each side of handle, and held there by 
a steel pin running through. Below, 
these pieces are held by a pin through 
them and through the two pieces of 
board which are above tlie base-board 44 
in. All these joints must work easily. 
Eig. 6 represents a side view of press com- 
pleted. 
The adjustments depend not so much 
on the measurements as on the slope in 
the uprights. It is well to put the type in 
the chase first, and when board c is 
brought towards them, see whether they 
touch it equally and all over; if not, 
either make your slant slope more or 
less, and your long pieces on c advance 
more or less, as the case may be. 
To put my type in the press, I turn up 
the chase and board (a) and insert type. 
To prevent this board from falling back- 
wards, I screwed a small piece of wood 
across the top. On this the chase-board 
(a) rests, and a small hook prevents it 
from falling in its place, 
c, Eig. 6, should be well padded with 
thick blotting-paper, as this 
makes a soft cushion for 
the type to press against. 
Paper and cards to be 
printed are held in various 
ways, pins, cord, elastic^ 
etc. The figures are all 
drawn by a scale of § = 1 
incli, and will make the ex- 
planations more clear. 
Do not keep your press 
in too warm a place, nor 
wet it, as the wood may 
warp. Type, rollers, etc., 
may be had of the^Young 
America Press Company, 
No. 19 Murray Street, New 
York City. A good surface 
to spread ink on can be 
made of a piece of sheet iron or zinc 
nailed to a board.

AND-SAWS for crosscutting re- 
quire a great deal more skill to 
put and keep in order than the 
ordinary rip-saw ; the latter, if 
intended for cutting soft wood, has all its 
teeth filed at right,angles with the line of 
points, or, in other words, it is filed 
square across, the file being held in a 
horizontal or level position. 
Eig. 1 shows a fair-sized rip-saw, the 
blade being about twenty-six inches longv

which is quite long en ough for an ama- 
teur to use. A saw of this size should
